. A CORPORATION or PEnNsYLvAnIA r iA'rEiI My invention relates to steam plates or a's they are called platens, such as employed 7 in the curing, vulcanizing, or other heat treatment of rubber and composition goods, syn- 5 thetic resins, bakelite, etc'., or for other purposes where a heated plate is'required;-such plates or platens having internal passages for the circulation of steam or' other heating medial and in some instances Cooling media;

10 in other words temperature-controlling media. .For such purpose provision is made for the introduction and-withdrawal of such temp'erature-controlling media and inorder to provide for circulationthroughont the :5 whole extent of the-plate orplaten, the passages therein are in communicationwith each other and provide a continuous conduit.

The present invention comprises a plate or platen having a series of cross passages 20 placed relatively close together. andextend ing in one direction with respect to themarginal edges of'the platen;-1such cross passages being suitably connected'by short passages formed in the walls between pairs of said 2 5 assages alternately adjacent opposite edges of the plate'or platen, with-a continuous passage formed by'a tube: (or tubes) introduced into a bore-(or bores) 'of-the platen which maybe located adjacent an edge-or margin atright-angles to said cross passages.

passage .just described provides aconduit of material length which may be employed for the inletor return of the temperaturefconf "t trolling media, If the tube forms. a partof the return passagejustpri0r-t0 discharge of the temperaturecontrolling media the latter willbe retained for a'longer period than with the usual forms of platens. The tube forming the continuous passage at right angles to the Fig. 3 is an edge view'looking-in thedicross passages may be otnon-ferrousimetal and is placed in the bore receivlng the same by a force fit." The cross passages mes n;-

In ,the drawings, 1 represents the body oi, the plate or platenwhich is preferably of v rolled steel and of uniform thickness'throughout its entire extent. "It is desirablefin the manufacture of these plates'thatthe faceslbe absolutely parallel; and .for some Quseslgitlis desirable .to grind and polish the surfaces y 'bseidey lfired int the true V i V I I I planes desireda I The plate may be rectangular fin contour andi'n' the drawing (for Illustrative purposes (only) it-is indicated as being slightly longer 8 0 than wide; the marginal sides or edges in'dijcated at A and'B bemg somewhat longerthair the marginali'sldes or edgesfmdmatedat andDLfThisishape, however, not repre 'sentative'of all plates embodying this inven-* .c 1

tion and the invention is not to. be limited to' any dimensions of either width or length relj Y atiyely to each other, as square; plates or plates of other dimensionsmay include the features o-fthe'. present invention. I

For the purpose of description only, the marginal edges indicated at A and B may represent the length of the plate and the marginal edges indicated at C and D may frepresent the width of the plate. The plate may be bored or drilled from side to side of the same or between the marginal edges A and B to form cross passages 2, 2 2 2', etseq.-; or

In bideinto provide communication between adjacent cross passages, the metal wall between the same may be cut in the manner set forth in the 'Ruch patent berths re ferred to. These short connecting passages;- indicated'at 3, are disposed adjacent opposite edges of the plate, alternately arranged,

and provide Withthe cross and otherp'as" sages the continuous conduit f or the circu- 1\ -\e', H. I lat1on of heating or cooling media.
